我使用谷歌Places API的第一個再寄一次要顯示附近的公用事業（可以說醫院）在密閉radius.When我點擊「查找按鈕「沒什麼happens.I我使用這個鏈接來開發這個項目：link我已經正確生成谷歌Places API的關鍵，但它總是顯示以下錯誤：谷歌Places API的不working.Authentication未能在服務器上
Authentication failed on the server.
E/Google Maps Android API: Authorization failure. Please see https://developers.google.com/maps/documentation/android/start for how to correctly set up the map.
E/Google Maps Android API: In the Google Developer Console (https://console.developers.google.com) Ensure that the "Google Maps Android API v2" is enabled. Ensure that the following Android Key exists: API Key: AIzaSyA4NL7****************************

這不工作！用'機器人NAME =「com.google.android.geo.API_KEY」'： – swapnil
嘗試更換'機器人NAME =「com.google.android.maps.v2.API_KEY」' –
你能夠在開發者控制檯應用程序？另外，進行更改後，請在設備/模擬器上完全重新安裝應用程序。 –
